[PATCH 14/25] Input: synaptics - adjust min/max on Thinkpad E540

[Timo Aaltonen]

From: Ben Sagal <bensagal at gmail.com>

commit bce4f9e764c36bc35dd5c9cf9e057c09f422397d upstream.

The LEN2006 Synaptics touchpad (as found in Thinkpad E540) returns wrong
min max values.

touchpad-edge-detector output:
>  Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event6
>  Move one finger around the touchpad to detect the actual edges
>  Kernel says:    x [1472..5674], y [1408..4684]
>  Touchpad sends: x [1264..5675], y [1171..4688]
